THILL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 550,272, dated November2e, 1895.

Application filed August 20, 1895.

To @ZZ whom it may concern:

Be it known that I, RUDOLPH G. JAHNKE, a citizen of the United States,residing in the city of Cincinnati, Hamilton county, and State of Ohio,have invented certain new and useful Improvements in r.Phill-Couplings,of which the following is a specification.

The object of my invention is to produce a cheap, simple, and efficientantirattler thillcoupling.

In the accompanying drawings, forming part of this specification, Figurel is a side View, some of the parts being partly broken away. Fig. 2 isa top view of the device. Fig. 3 is a front view of the device, theshaft being removed, and Fig. 4 is a perspective view of the shaft-iron.

A represents a plate on which the axle J rests, the clips P connectingthe thill to the axle J. From this plate A extend the ears B. They areshaped as shown and have recesses a present in their upper portion. Fromthe bottom of the plate extends the standard or pin E. The plate A, earsB, and pin E are preferably made in one.

C represents a bar having a foot ct and a hook shaped head D. The pin Epasses through the foot a', a nut G being screwed onto the lower end ofsaid pin E. A spring F is interposed between the foot ct of the bar Cand the plate A and is coiled around the pin E. The bar C extends upbetween the ears B slightly and moves up and down when the end M of theshaft-iron catches under the hooked head D.

L represents the shaft-iron connected to the shaft K in any suitablemanner. It is of the peculiar shape shown in Fig. 4, having .the curvedend M and carrying the Wings N. The shaft-iron lits into the coupling,as shown in Fig. l, the end M passing between the ears and hooking underthe hooked head D of bar Serial No. 559,905- (No model.)

C, the part p of the wings N passing into the recesses ct of the ears B.When the shaftiron is depressed, the hooked end portion M, having caughtunder the hooked head D of bar C, it pulls the bar C upward and thespring is compressed, thus preventing any rattling. When the horse isunhitched and the shafts are loose, the compression on the spring isreleased and the shaft assumes the position shown in dotted lines inFig. 1.

A bar H is placed across from ear to ear, so that the shaft-iron cannotslip up and out should connection with the head D not be properly made.

If it is desired to remove the shafts, they are placed in about avertical position and lifted out. The wings N also tend to strengthenthe shaft-iron.

The various parts are preferably formed as shown, but may be differentlyformed, and they may be welded together or cast.

What I claim as new and of my invention, and desire to secure by LettersPatent, is-

l. In a thill coupling, a plate A, pin E, and ears B in combination witha spring F a'shaft iron L, and bar C, as set forth.

2. In a thill coupling, the combination of a plate A, pin E, ears B,spring F, bar C, having foot d and head D and shaft iron L, as setforth.

3. In a thill coupling, the combination of plate A, ears B, havingrecesses a, pin E, bar C, having head D and foot a', spring F interposedaround said pin E between the foot a of bar C and the plate A, shaftiron L, having hooked end M and wings N, as set forthl RUDOLPH G.JAHNKE. Attest: H. RICKE,
